Microdevice for Evaluating Drug Response in Site in Lung Lesions

The initial aims in this pilot study will focus on the safety and feasibility of microdevice placement and retrieval in participants with suspicious lung lesions. The microdevice, which is 5.5 mm in length and approximately 750 µm in diameter (i.e., comparable in size and shape to commonly used fiducial markers), will be placed in the suspected tumor tissue at the time of surgical resection. Multiple agents will passively diffuse into local, confined regions (several microns) of the surrounding microenvironment. The agents are released at approximately one millionth of a systemic dose. The device(s) will be removed for analysis at the time of resection, which will be performed for clinical indications independent of enrollment in this study. The investigators will collect data regarding the safety and feasibility of the placement and retrieval of the microdevices, and perform detailed tissue analysis of drug response. Investigators hope to compile preliminary data regarding correlations between in situ drug response and the genetic and histopathologic features of tumors, systemic treatment response, and ultimately, clinical outcomes.
